O. ; Shymko, A. V.; Bundza, О. Z.; Holotiuk, M. V.; Herasymchuk, O. P.; Puts, V. S.; Shovkomyd, O. V. ; Налобіна, О. О.; Голотюк, М. В.; Бундза, О. З.The amount of energy required to perform technological processes in agriculture largely depends on the size of the resistance to the displacement of the working bodies of machines. The main factor of energy consumption performing the technological process of potato harvesting is the resistance to the displacement of the diggingworking body. In order to reduce the resistance to displacement an improved design of the digging body is proposed. An analytical study was conducted to determine the problem of moving the working body in the soil environment. The strength of the soil resistance is determined and the regularity of the influence on its change of parameters and the shape of the blade and separation parts of the digging working body is established.Calculations are made using the Mathematica application program. The graphic dependences and contours of the isocline ofthe traction flange of the working bodyploughshare part are obtained. Analysis of the calculations allowed to set the parameters of the instrument panelsurface,of which provide a minimum of traction resistance. The schedule and contours of isoclines of the change of the total resistance to the displacement of soil mass with the tubers onthe working bodyseparation surface depending onthe distance between the bars and the size of their intersection are also obtained.Analysis of the dependence of soil resistance and tubers on the separation surface indicates that an increase in the size of the geometric size of rods intersection leads to a significant increase in the resistance of the medium. The material presented in the article can be used for analytical determination of the resistance of the diggingworking body of potato harvesting machines of arbitrary geometric shape in the soil medium with tubers.Документ Analytical investigation of the interaction of the sunflower stem with the lateral surface of the reaper lifter(National Institute for Research-Development of Machines and Installations Designed for Agriculture and Food Industry, 2018) Nalobina, O. O. ; Herasymchuk, O. P. ; Puts, V. S.; Martyniuk, V. L.; Shovkomyd, O. V.; Vasylchuk, N. V.; Bundza, О. Z.; Holotiuk, M. V.; Serilko, D. L.; Налобіна, О. О.; Бундза, О. З.; Голотюк, М. В.The design of a reaper that provides grinding of stems, which eliminates the need for mulcher application, offers the conditions for introducing a new technology of growing No-Till crops in agrarian enterprises. The substantiation method of the analytical model is proposed, which allows to determine the nature of the stem movement on the side surface of the sunflower header elevator in the process of their interaction.
